Just bought some Axiom QS8s for my surround speakers. Question is on the placement. I've got to mount them to my wall and I have basically two options. The link below shows a few pictures of my room layout. I can either mount them both on the rear wall above the light switches on each side of the rear wall. Or I can mount the right surround on the rear wall and the left surround on the adjacent wall next to the bookshelf. The bookshelf could be moved if it would be obstructing the sound. I kind of think both on the rear wall would be best for sound quality but that is my gut instinct. Any suggestions? Thanks in advance. http://www.flickr.com/photos/36396915@N03/
